' To all 'wlwm it may concern Be it known that I, N morn} Elli-\LM'AN, a cit zen of the United States, residing at the city and county of SanFrancisco and State of California, have invented new and useful Improvements in Resilient Vlheels, of

This invention relates to resilient wheels and especially to that type in whicharesilient structure is interposed between 'the-felloe and the wheel hub.

The object of the'pi'esent invention is to generally improve and simplify "wheels of the character described; to provide a. resilient structure adapted to be interposed between the felloe'and the hub of a. wheel whereby a'limited radial and circumferential movement of, the felloe with relation to the hub will be permitted; to provide a structure of this character which is substantially dust and watenproofl and which secures the felloe against lateral movement with relation to the-hub, and'further to provide means whereby theresiliency of the interposed structure may-be readily adjusted to varying loads. after appear.

One form whichmy invention may assume- 'is exemplified in the'followmg' description andillustrated in the accompanying" drawin s, in whiche fig. 1 is a side elevation of the wheel par struction, and similarly the U-bol'tsf6 land 12 5 m a 90 tially in section and partially broken away. Fig. 2 is an end view of the wheel, partially in section and partially in elevation.

Fig.3 is, a detailview showing the flexible chain whereby the resilientlrubber blocks are held inposition and whereby traction is transmitted from the hub to the1 i 'elloe..

V Referring'to the drawings in detail, and particularly to Figs. 1 and 2 A indicates a standard form of wheel hub, 2 an inner tel loe, 3 spokes co-nnectingthe inner telloe and i the hub, 4 an exterior felloev and 5- arubber tire carried thereby. Interposed between the inner felloe and'theexterior felloe l is :1 resilient structure through which turmng movement is transmltted from the inner i'e'lloe to the exterior felloe. and whereby a liniterior felloe and hub is permitted.

When the wheel is assembled and a load applied to the hub member A, it can readily be seen that the rubber blocks B and C will be subjected to compression strains as the hub A will naturally tend to se tie in a downward direction towards the outer felloe 4, or in other words move radially with relation to the exterior telloe. Such movement will in this instance be resisted by the blocks l3 and D as the entire load will be equally, divided on the alternate blocks. The degree or" resiliency produced depends en'- tirely upon the amount of compression to which the blocks l3 and C are subjected and thisdegree of compression may be regulated by tightening up or loosening the ends 8 and 15, and the wheel may'i or this reason be adjustedto varying loads. It thewheel illustrated happens to be the rear driving wheel,.tor instance of an automobile, it is obvious that a certain amount of circumferential movement of the exterior ielloe with relation to the interior ielloe would be desirable. as it would tend to relieve the driving mechanism of sudden strains and pulls, such resiliency and movement being obtained in the present instance by the con nection formed between the eyes 11 and 13 and the respective U-bOltS 6 and 12. Radial movement of the exterior felloe or conversely the hub and inner felloe willv also be permitted when the wheel is subjected to road shocks as the blocks C and D will give to a limited degree when subjected to such shocks.

ln view or" the position of the resilient members B and C and the action obtained through the employment of the same, it is obvious that pneumatic tires may be entirely dispensed with and that any standard form of solid rubber tire may be employed as illustrated; further that this tire may be secured; upon an ordinary clincher rim or otherwise secured.

For the purpose of excluding dust and water, also for the purpose of securing the outer telloe against lateral movement with relation to the hub A and the inner felloe, a pair oi. exterior side plates 25 and 26 is employed. These plates engage the respective sides of theexterior lelloe and are secured thereto by means of transverse bolts 27. These bolts are circum'rerentially arranged and interspaced as shown and thus rigidly secure the side platesto the exterior i'elloe. Frictional engagement is maintained between the inner felloe and-the side plates and the surface of contact'may be increased or decreased as desired by turning up the side flanges of the inner telloe as indicated at 28. A substantially dust and water-proof joint may in this manner be obtained without in any way interfering the several parts employed may be such as the experience and judgment of the manutacturer may dictate or various uses may demand. a
